arc_to
A circular arc to a point.
Signatures
- arc_to( vector via, vector to )
- arc_to( vector to, float radius )
- arc_to( vector to, float radius, bool right )
- arc_to( vector to, float radius, bool right, bool short )
- arc_to( vector to, float radius, bool right, bool short, vector normal )
Details
The arc_to curve segments adds a circular arc to a curve. The arc extends to the given target point to.
In the first constructor, the arc is defined by a given point that it shall pass.
The other constructors are defined by a specific radius plus additional specifications.
The figure shows the four different options for a circular arc towards point to that can be addressed via the parameters right and short. (The normal points outward of the plane into the reader's direction.)
Parameters
- via
-
An intermediate point on the arc.
- to
-
The target point the arc is drawn to.
- radius
-
The radius of the circular arc.
- right
-
Determines whether the arc follows the right-hand rule (true) or not (false) (default: true).
- short
-
Determines whether the arc takes the shorter (true) or the longer (false) of the two possible routes (default: true).
- normal
-
Determines the axis direction of the arc circle. This should be mostly perpendicular to the connection vector between the formerly last point of the curve and to . If it is found to be parallel to this connection, an alternative orthogonal axis is used. (default: <[0,0,1]>).
